Snow. In Maui.

"For perhaps the first time ever, snow has fallen in a Hawai'i State Park. Polipoli State Park on Maui is blanketed with snow. It could be the lowest elevant snow ever recorded in the state. Polipoli is at 6,200 feet elevation," the DLNR said.

Wind advisories in effect

CNN Meteorologist Monica Garrett said winds will diminish and weather conditions will improve throughout the day as the "low moves northeast of the area."

"A band of enhanced moisture is expected to move through Tuesday night and Wednesday as the trade winds begin to return, increasing shower coverage and intensity once again."

The National Weather Service in Honolulu issued a wind advisory in effect until noon HST (5 p.m. ET). An advisory means that "sustained winds of at least 30 miles per hour or gusts of at least 50 mph are expected. Motorists should use extra caution."

On Sunday, wind speeds were recorded at 25 to 40 miles per hour and there were reports of wind speeds above 50 and 60 mph.

Speeds in Port Allen in Kauai County were as high as 67 mph and 191 mph at Mauna Kea Summit in Hawaii County.

A high wind warning was in effect for the Big Island summits until 6 p.m. HST (11 p.m. ET) Tuesday. That means winds are expected to be at least 40 mph with gusts over 60 mph in these higher elevations.

Evacuation shelters opened in some areas but falling branches closed the Honolulu Zoo, Honolulu Mayor Kirk Caldwell said. Beaches and parks are also closed.

At the zoo on Sunday, a tree collapsed on an enclosure holding two African ground hornbills. The birds escaped, CNN affiliate KNHL reported, citing city officials.

At Kapiolani Park in Honolulu, strong winds uprooted kiawe trees said to be nearly a century old, according to KNHL.

In Oahu's North Shore on Sunday, coastal flooding occurred because of the "huge storm surf," KNHL reported.
